Hi, I’m what you would probably call a socialist (but I’m not, really).
I want to dismantle certain things, sure. Bad things, like insane military spending and the apparatus of greenhouse gas emissions that will kill us all. I also don’t like economic imperialism that has a history of using veritable slave labor and that gets foreign leaders deposed, and whose replacements murder dissidents. I also know nationalism is silly at best.
I want people in this country to have resources that residents of every other country with money (but all of them with less than us) has, such as healthcare for people. Those people like their healthcare by the way, and most of those countries rank above the US in health and general well-being.
I don’t think that constitutes wanting to destroy the US unless you think the US is bad.
